How to create form controls dynamically

Hi,

I am using xforms orbeon framework. I have a configuration xml file which is defined with all the UI controls. How do I create UI form controls dynamically, by referring this configuration XML document.

Thanks,

Venkatesh

you could use a xpl pipeline to create a xforms view. Inside that
pipeline, you can use the XSLT processor to create a xhtml output with
xforms controls based on your config file. It's important that the
pipeline has a data output for the xhtml.

I've attached a simple example with some "configuration" xml data
enclosed. If you put it under
webapps/<yourapp>/WEB-INF/resources/pages/test/dynamiccontrols.xpl, you
just have to add a page-flow entry like this:

<page id="dyn"
path-info="/dyn"
view="pages/test/dynamiccontrols.xpl"/>

Then it should be available under

http://localhost:8080/<yourwebbapp>/dyn

The xpl creates a xhtml+xforms page based on the data input. It takes
the data input as instance as it is, and inserts a xforms:input control
for each instance element under /document.

Re: Re: Re: How to create form controls dynamically

Hi,

I Put the file in C:\Tools\apache-tomcat-5.5.17\webapps\orbeon\WEB-INF\resources\apps\dyn folder where my orbeon is deployed.

this dyn folder contains two files: page-flow.xpl and dynamiccontrols.xpl

page-flow.xml looks as:
===================
--
<config xmlns="http://www.orbeon.com/oxf/controller">

<page id="dyn"
path-info="/dyn"
view="dynamiccontrols.xpl"/>

<epilogue url="oxf:/config/epilogue.xpl"/>

</config>

and dynamiccontrols.xpl what you provided.

Apart from this, Are some more supporting files it require ? As i am getting error:

Condition failed for every branch of choose: [(/request/request-path = '/xforms-server-submit'), (/request/request-path = '/dyn')]

Can you provide me the full working example with supporting file. I am not able to run this.

thanks in advance !!

Thanks
Manish Suriya

sorry, was indeed too specific - i've attached a zip containing the xpl
and a modified page-flow. Just unzip it in the apps directory of your
orbeon webapp. Then it should work with
http://localhost:8080/orbeon/dyn/
